This is a cool Canadian trilobite. It is a complete Ceraurus sp. from Ontario, Canada. This wonderful specimen was recently acquired from the famous Eugene Thomas Collection. The trilobite is extremely inflated and has beautifully preserved thick shell exoskeleton. The fine detail of the trilobite is wonderfully displayed. The bug is very well-articulated and nicely showcased on the large, rounded matrix block. This is an excellent example of a Ceraurus sp., once part of the Thomas Collection.
